Industrial societies spend huge amounts of energy. Much of it is supply by electricity which comes from generators in power stations.
POWER STATION POWER STATION
In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit.
What is generator?
GENERATOR
A power station is an industrial facility for the generation of electric energy.
Power Station
In thermal power stations, mechanical power is produced by a heat engine that transforms thermal energy, often from combustion of a fuel, into rotational energy.
A thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.
After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
Thermal Power Station
In a thermal power station fuel such as coal, oil or gas is burned in a furnace to produce heat - chemical to heat energy. this heat is used to change water into steam in the boiler. the steam drives the turbine - heat to kinetic energy this drives the generator to produce electricity - kinetic to electrical energy.
